Chosen theme not persisted

[stephfh]

Description

Hi!

In v1.15 the theme chosen via /themes doesn't seem to be persisted and only seems to be active for the current session.

Steps to reproduce:

1. Launch opencode
2. /themes and choose a theme (system in my case) => theme active
3. close opencode and relaunch => default theme active again

Versions:

Opencode: 1.15
Terminal: Ghostty, v1.3.1
Operating System: macOS 26.5

I also set "theme": "system" in my opencode.json (according to the docs). Weirdly enough I don't see the property in the output of opencode debug config, but it seems to be set correctly in ~/.local/state/opencode/kv.json (at least I see a "theme": "system" in there).

This issue might be a duplicate of an existing issue. Please check:

• Theme selected within opencode isn't saved when closed and reopened #3620: Theme selected within opencode isn't saved when closed and reopened (same symptom - theme selection not persisting across sessions; closed but may have regressed in v1.15)

If this is a regression or the fix didn't hold, please mention that in the issue so maintainers can investigate accordingly.

theme should be mentioned in tui.json check link

Also are u using any terminal multiplexer since I use tmux I dont have system option in /themes I can only see it when i use just ghostty

Also did u see same issues on non-system theme too?

Hi @Arjith8 ,

oh, weird. I must've been looking at the wrong part of the docs, I was looking at: https://opencode.ai/docs/de/themes/#theme-verwenden, doesn't mention the tui.json there.

It was indeed set (wrongly) in tui.json, changed it and seems to work now!

Sorry for the false alarm. :D
